Description

泵体组件、变容压缩机、空气调节***Pump body assembly, variable volume compressor, air conditioning system

技术领域Technical field
本申请属于压缩机制造技术领域，具体涉及一种泵体组件、变容压缩机、空气调节***。The present application belongs to the technical field of compressor manufacturing, and specifically relates to a pump body assembly, a variable-capacity compressor, and an air conditioning system.
背景技术Background technique
空气调节***中为了根据负荷的需求调整能力输出，大部分都应用了变频压缩机，压缩机可以通过压缩机频率的调节来调整能力输出。而空气调节***负荷太小时，需要不断地降低压缩机的运转频率，然而由于压缩机最低运行频率的限制，压缩机所能输出的最小冷量受到限制。因此当***负荷小于压缩机最低频率运行所能输出的最小能力时，压缩机会频繁出现开停机，导致压缩机耗功大，同时压缩机频率太低时，压缩机容积效率和电机效率低，导致压缩机低频运行能效低。因此目前有通过采用变频变容的方式来解决此问题，即压缩机采用双缸结构(甚至多缸)，通过增加切换结构控制压缩机在单缸运行与双缸运行模式之间切换，大负荷时用双缸，小负荷时用单缸，此类变容压缩机在实现变容时，需密封变容气缸的滑片槽，以便通过对滑片槽内引入高压或低压来控制滑片的运动。而实际运用中发现，密封后的滑片槽容积太小，滑片槽内的滑片高速往复运动时，滑片槽密封腔内的压力会产生非常大的脉动，使得滑片尾部的压力过大或过小，影响滑片的可靠性。In order to adjust the capacity output according to the demand of the load in the air conditioning system, most of the inverter compressors are used. The compressor can adjust the capacity output through the adjustment of the compressor frequency. When the load of the air conditioning system is too small, it is necessary to continuously reduce the operating frequency of the compressor. However, due to the limitation of the minimum operating frequency of the compressor, the minimum cooling capacity that the compressor can output is limited. Therefore, when the system load is less than the minimum capacity that the compressor can output at the lowest frequency, the compressor will frequently start and stop, resulting in a large power consumption of the compressor. When the compressor frequency is too low, the compressor volumetric efficiency and motor efficiency are low, resulting in Compressor low-frequency operation has low energy efficiency. Therefore, there is currently a solution to this problem through the use of variable frequency and variable capacity, that is, the compressor uses a double-cylinder structure (even multi-cylinder), and the switching structure is controlled by adding a switching structure to control the compressor to switch between single-cylinder operation and double-cylinder operation mode. When using double-cylinders and single-cylinders under light load, when this type of variable-capacity compressor achieves variable capacity, the sliding groove of the variable-capacity cylinder needs to be sealed in order to control the sliding vane by introducing high pressure or low pressure into the sliding groove motion. In actual application, it is found that the volume of the sliding vane groove after sealing is too small. When the sliding vane in the sliding vane reciprocates at high speed, the pressure in the sealing cavity of the sliding vane groove will generate a very large pulsation, making the pressure at the rear of the sliding vane If it is too large or too small, it will affect the reliability of the slider.
